Self‑Built QPU Stack Claims to Factor RSA‑1024: What the Analysis Shows

Renowned cryptographer Jean‑Philippe Aumasson posted a self‑built QPU stack that allegedly factors RSA‑1024, but a detailed technical review reveals the code relies on classic algorithms, the video is merely an animation, and the claim serves as a warning for organizations still using RSA‑1024.

Constant-Time Implementation and Optimization of SM2 Finite Field Inversion

The article analyzes constant‑time computation of the multiplicative inverse in SM2’s prime field, compares the variable‑time Extended Euclidean Algorithm with a constant‑time Fermat‑based square‑and‑multiply exponentiation, optimizes the fixed exponent using add‑chain generation, and shows this reduces multiplications from ~187 to ~41, making inversion the dominant cost in secure SM2 signing.
